CHANNELING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 500,060, dated June 20, 1893.

Application filed June 28, 1892. Serial No. 438,246. (No model.)

To aZZ whom it may concern.-

Be it known that we, ZAOHARY T. FRENCH and WILLIAM C. MEYER, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Channeling-Machines, of which the following description, in connection with the accompanying drawings,.is a specification, like letters and figu res on the drawings representing like parts.

This invention has for its object to improve that class of machines employed more especially for channeling out-soles while on the last, and after-havingbeen-fitted to the upper.

One part of our present invention relates to the knife which cuts the channel, we having combined with it suitable devices to impart to it a vibratory motion.

We have also devised a novel support for the sole, it consisting of a bevel faced wheel having gear teeth and driven positively, the said bevel face serving to support the outer edge of the sole outside the channel. Oo-operat-ing with this wheel is a bevel faced or conical presser Wheel rotated positively, said bevel faced wheel grasping the welt and sole edge, and aiding in feeding the same. Oo-opcrating with the uppermost of the said wheels is an upper-gage, or gage to bear against the upper on the last.

Our machine is adapted to cutting a channel more or less distant from the edge of the last, the edge of the last covered by the upper, in connection with the upper-gage, determining the line of the channel to be cut in the sole attached to the shoe.

Herein we have shown and will describe one well known form of knife for cutting a channel, and-it will be understood that this invention is not limited to the particular form of knife shown, as instead we may use any other equivalent or well known knife or knives commonly used for cutting or grooving a channel in a sole, and by the term channel knife as herein used in the claim we intend to include any suitable channeling or Figure 1, in front elevation represents a channeling machine containing our improvements; Fig. 2, a right-hand side elevation thereof; Fig. 3, a much enlarged longitudinal section of the upper part of the machine shown in Figs. 1 and 2; Fig. 4, a detail showplane.

.ing the upper end of the knife-frame and knife; and Fig. 5, shows the center support for the sole, and the frame to which it is attached.

The frame work consists essentially as' shown, of a head A, supported on a suitable column A, the head having suitable bearings and being properly shaped to receive the working parts to be described. The column, as shown, receives a power-shaftA provided with suitable fast and loose pulleys A A, cooperating w ith which is a driving belt A said belt in pradtice being driven and controlled in usual ways. The power-shaft has two pulleys B, O, the one B driving a belt B which, extended over suitable idler pulleys, is passed about a pulley B on a short shaft 13 shown best in Fig. 3, and provided with a suitable crank pin 13, extended preferably in a loose block or roll B entering a slot in the lower end of the knife lever B provided at its upper end with the channel knife or blade E the said lever having its fulcrum on a hollow sleeve B attached to or forming part of the stand D firmly secured to the head by a suitable set screw D, the rotation of the shaft giving a .rapid vibratory motion to the knife greatly facilitating its action and enabling it in its cutting action to reduce the resistance which it would otherwise offer to the feeding movement of the outer sole and lasted upper. The belt 0 extended over the pulley O is made to rotate the pulley C loose on a stud C and provided with a pinion G the latter engaging a gear 0 on a shaft O havingat its outer end a bevel pinion C which engages a crown bevel O surrounding the center of rotation of the supporting wheel G having a smooth bevel face a, against which bears the bottom of the outer sole outside the channel, said bevel faced part of said wheel also acting as one member of the feeding mechanism. The supporting wheel 0 has its shank extended through a diagonally arranged bearing in the stand D, theinclination of the bearing and of the face a, of the Wheel 0 being such as to bring the face a, when uppermost and next the knife referred to in a substantially horizontal The stand D also receives and guides a frame E on which is pivoted to rotate a center support E for the sole to be channeled, said support, shown as a roll, serving to aid the farther from the edge of the sole as in the operator to keep the face of the sole always in the same position with relation to the knife. The frame E has an adjusting device shown as a screw 1), which may be turned as desired to enable the roller E to be set at the properlevel. The shaft 0 has a gear d which engages a gear cl fast on ashaft d 'having its hearings on a yoke d pivoted at its rear end by a pivot (Z to the upper end of an elbow lever d pivoted at d on thehead, said elbow lever having jointed to it a rod d attached at its lowerend to a treadle 01 said elbow lever being acted upon by a spring (1 which normally serves to keep the treadle elevated. The front end of the yoke d is provided with a conical seat 2 which serves to guide a wheel e which performs two functions, vim-that of a presser to bear on the, welt outside the up per of the shoe and also one member of the" feeding mechanism. This wheel e has crown bevel teeth e which are en aged by a bevel -3 pinione fast on the shaft The wheel e is; kept in place on the seat 2 bya suitable stud screw a The outer end of the yoke has attached to it the upper gage e which acts as g a guide'for the upper on the last to which the soleto be channeled is attached, the said upper gage being substantially in contact with" the wheel 6. The yoke d is acted=upon""near;

its outer end by a suitablespringflmade ad-i j ustable and to enable the wheel e tobelifted from the welt when it is desired to put in or take out a shoe, we have jointed to the yokel at g, a rod g which is attached at its lower; endto a treadle g The channel to becut in i the outer or face side of the lasted outer sole, i in some classes of work, has to be thrown in shank, and to provide for this we have arranged the parts so that. they stand normally: in the position for shank work. The upper gage has been made adjustable horizontallyi with relation to the channel knife, so that; when the channel is beingcut about the fore part of the sole, the operator, by putting his foot on the treadle (1 will throw the upper gage e to the left viewing Figs. 2 and 3, thus causing the said gage to move .theshoe in a. direction to enable the knife to cut closer to the edge of the sole.

To limit the distance fromthe edge of the last at which the knife shall cut the channel in the sole, we have provided the yoke with the forked arm h which embraces a screw h shown chiefly by dotted lines in Fig. 3, said screw being fixed in suitable bearings at one end to the head, and receiving upon it at each side of said arm it suitable adjusting nuts or levers h, h. The adjustment of these nuts on thesaid screwtoward or from each other, leaves more or less space in which the said armmay move, and consequently the said nuts determine the extreme position of the gage c with relation to the knife. A roll 2 carried by the yoke (1 pivoted on the pivoted elbow d may, it may be readily understood, be made to move longitudinally through #the action of a suitable treadle toward and from the edge of the channel knife, so that when the distance of the channeling from the edge of the sole is to be varied, and also that the yoke carrying the roll may rise and fall, and as herein shown, the said gage mounted upon and carried by the yoke is .made to partake of the movements of the yoke.

Having described our invention, what we claim, and desire to secure by Letters Patent, is
